VERSION 1.0.5: Windows and Linux (upgrade) bug fixes

Version 1.0.5 is a very minor release. It includes a new build of the Windows
device driver that supports Windows Vista and 2008 Server, and a fix to prevent
an issue that could occur when updating Linux installations from old pre-1.0.3
versions to 1.0.3 or 1.0.4.

It also includes a few very minor fixes and improvements to the controller code,
which doesn't affect most users.
